Description

Shell structure and remote controller

Technical Field

The utility model relates to the technical field of remote controller disassembly prevention structures, in particular to a shell structure and a remote controller.

Background

The remote controller is an electronic device for remotely controlling a machine, and its operating principle is based on converting an instruction into a digital signal, then encoding it into an analog signal using an encoder, and finally implementing control of the controlled device by transmission and reception of infrared rays or radio waves.

The traditional remote controller shell is installed through the mode of screw assembly, can not prevent to imitate the dismantlement action or the theft action of purpose, also can not avoid because of the user dismantles some potential safety hazards that the remote controller led to by oneself. There are also remote controller cases on the market with anti-disassembly function, for example, a compression bar that is telescopically movably disposed on the bottom surface acts on a touch switch to form an anti-disassembly purpose, and after installation, if the main body is separated, the compression bar can change the continuous information that acts on the switch, so that the main body can fail or generate an alarm signal. However, such a tamper evident structure also has the following drawbacks:

1. the body may be detached by an unexpected factor to trigger the tamper function, resulting in the failure of the body, such as detachment of the adhesive, which is undesirable to the user.

2. The tamper evident structure is typically open by default and cannot be used by the user to select whether to activate or not at the time of installation.

3. Some products perform initial short circuit on the anti-disassembly structures such as the compression bar through the short circuit structure so as to enable the anti-disassembly structures not to be started, but the anti-disassembly structures can be started due to overlarge operation amplitude or false touch in the installation process.

4. The anti-disassembly function and the disassembly function are mutually independent and have no correlation, so that the structural design of the anti-disassembly function and the disassembly function are independent, the manufacturing cost is high, and the assembly is complex.
